Shop HITACHI EX60-1 SERIES SWING DEVICE SLEW BOX OIL SEAL | Tonkee®

The oil seal is typically constructed from high-quality elastomeric materials, such as nitrile rubber (NBR) or ethylene propylene diene monomer (EPDM), known for their excellent resistance to oil, heat, and abrasion.

These materials are chosen to ensure longevity and performance in demanding construction environments.

Design and Dimensions:
The design and dimensions of the oil seal are engineered to precise specifications to fit seamlessly within the EX60-1 Series hydraulic excavator. These specifications include the inner diameter (ID), outer diameter (OD), and thickness of the seal, which are tailored to the specific requirements of the swing device or slew box. The seal typically features a lip or sealing edge that makes contact with the rotating shaft, preventing oil from escaping and contaminants from entering the system.

Pressure and Temperature Rating:
The oil seal is designed to withstand the operating conditions of hydraulic systems. It must be capable of handling the pressure generated within the hydraulic system, which can range from hundreds to thousands of PSI (pounds per square inch). Additionally, it must resist temperature extremes, from cold winter environments to hot summer conditions, without compromising its sealing capabilities.

Sealing Efficiency:
The primary function of the oil seal is to create a reliable barrier between the internal hydraulic fluid and the external environment.

It achieves this by maintaining a tight seal around the rotating shaft of the swing device or slew box. The sealing efficiency is a critical factor in preventing oil leaks and ensuring the proper functioning of the hydraulic system.

Durability and Longevity:
Oil seals in heavy machinery like the HITACHI EX60-1 Series hydraulic excavator are subjected to significant wear and tear. They must have a long service life and withstand frequent movement and pressure fluctuations. The choice of high-quality materials and precise manufacturing processes ensures the durability and longevity of these seals.

Installation and Maintenance:
Proper installation is essential to ensure the oil seal functions correctly. It should be carefully positioned and secured within the swing device or slew box housing to avoid damage or misalignment. Routine maintenance, including inspections for wear and tear, is also crucial to replace seals that show signs of deterioration promptly.
